A placement seat 103 is arranged at the upper end of the first shell 101. A groove 104 is opened on the placement seat 103. The mobile mechanism 200 includes a second shell 201. A battery and a speaker are also arranged in the second shell 201. The battery supplies power to the speaker and the electronic components in the device. The second shell 201 can be embedded in the groove 104 at the upper end of the placement seat 103. When in use, the second shell 201 is taken out from the groove 104, and the fixing mechanism 100 is placed on the table of the last row in the classroom. The mobile mechanism 200 is placed in the user's pocket or held by the user and moves with the user. When the user makes a sound, the sound is processed by the microphone 300 and the device and amplified and emitted from the speaker in the first shell 101 and the speaker in the second shell 201 at the same time.

[0028] By setting up a fixed mechanism 100 and a mobile mechanism 200 and installing speakers therein, the effect of amplifying the sound from the two speakers is achieved. Compared with the existing method of amplifying the sound by speakers only carried by the user, the speakers in the fixed mechanism 100 and the speakers in the mobile mechanism 200 are located at different positions in the classroom when working. The speakers in the fixed mechanism 100 can supplement the sound in places where the sound is weaker, so that all students in the classroom can hear the sound clearly.

[0029] Second embodiment:

[0030] like Figure 3-4 As shown, a back plate 202 is detachably provided on one side of the second shell 201, and the specific detachable manner is: a first magnetic plate 203 is provided on the second shell 201, and the first magnetic plate 203 protrudes outward, and the back plate 202 is concave downward on the side facing the second shell 201, and the size of the concave part is the same as that of the first magnetic plate 203, that is, the convex part of the back plate 202 can be embedded in the concave part in the second shell 201, and the concave part of the back plate 202 is provided with a second magnetic plate 204, the first magnetic plate 203 and the second magnetic plate 204 are magnetic and attract each other, and the attraction connects the second shell 201 with the back plate 202.

[0033] like Figure 4-5 As shown, a mounting groove 205 is provided on one side of the back plate 202 , and the mounting groove 205 is matched with the bottom of the second shell 201 , that is, when the back plate 202 is placed horizontally, the mounting groove 205 faces upward, and the second shell 201 can be placed in the mounting groove 205 .

[0034] The second housing 201 is supported by providing a mounting groove 205 on the back of the back plate 202 . When there is no iron equipment around the user, the back plate 202 can be used as a support to support and fix the mobile mechanism 200 .

[0035] Fourth embodiment:

[0036] like Figure 6 As shown, a shoulder strap 206 is provided on the back panel 202 , and the shoulder strap 206 is detachably connected to the back panel 202 , for example, hung on the back panel 202 via a quick-release buckle ring.

[0037] By providing the shoulder strap 206 , the user can hang the second housing 201 on the shoulder and move with the user, and it is also convenient to disassemble and store after use.

[0038] Fifth embodiment:

[0039] like Figure 6 As shown, the battery in the first shell 101 is installed in the base 102 at the lower end of the first shell 101. The battery has a certain weight. Installing the battery in the base 102 can lower the center of gravity of the device. At the same time, a rubber pad is also provided at the lower end of the base 102. The rubber pad can prevent slipping. The speaker in the first shell 101 generates vibration when working, causing the device itself to move on the desktop. The anti-slip pad can increase the friction coefficient between the device and the desktop to prevent the device from sliding.

[0040] Working principle:

[0041] When in use, the fixed mechanism 100 is fixedly placed at a certain position in the classroom, while the mobile mechanism 200 moves with the teacher or the user. The fixed mechanism 100 and the mobile mechanism 200 are connected to the microphone 300 via radio. The user's voice is converted into an electrical signal by the microphone 300, and then amplified and emitted from the fixed mechanism 100 and the mobile mechanism 200 after being processed by the device.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model.
